I want to use the ContentEditable attribut instead of classic inputs.
It sounds like a duplicate of Affordance of Edit In Place functionality, but actually I would like to avoid the changing of background-color as suggered by the answer. Also, the linked question is dated from 2011 and UX practices evolve constantly, so maybe there are new approaches and solutions for this subject.
This is my currently approach : a different color in addition of a bottom border.
(sorry for the french on this gif)
You can try it with this demo : http://jsfiddle.net/Lazgp/6
I chose the blue and the dotted border for no really good reason, just like that.
Have you any feedbacks or advices to improve it?
